HEEL-LIFT.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed October 24, 1918. Serial No. 259,547.

To all whom it may concern:

Be it known that I, GILBERT S. ELLrrHonrn, a citizen of the United- States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Heel-Lifts, of which the following is a specificatlon.

This invention relates to heel l fts of the general character set forth 1n my Letters Patent of the United States No. 1,272,929 and No. 1,273,047, dated July 16, 1918, and is directed to a specific improvement hav ng some of the characteristics of the invention set forth in said patent.

The mainiobjects of this invention are to provide a resilient tread lift of an upwardly concave form best adapted to hug the heel tightly, especially about its edge, when socured by central fastening means, and which may be thus applied in such manner as to fit smoothly and flat without any appreciable projections, hollows, ridges, or other irregularities Further ObJGCtS are to provide such a heel lift, the peripheral edges of which are for the most part adapted to fit initially against the heel in applying the lift; to provide such a lift the front or breast part of which is so formed and adapted as to yield in such manner as to avoid humps or ridges adjacent thereto or kicking up at the front corners as the lift flattens out in applying to the heel; and to provide a lift of this character in which the attaching means are well protected from wear.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figure 1 is a plan of the concave inner side of a heel attachment or tread lift.

Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1.

Fig. 3 is a front elevation or edge view %f the device as viewed from the right of Fig. 4: is a bottom plan view.

In the illustrative embodiment shown in the drawings, the lift 1 com rises a concavosecured to or embedded in the central part thereof ready for attaching the lift to a heel, as by driving with a hammer or the like. Said body 2 is composed of resilient material adapted to be molded about the fastener 3, rubber or a compound thereof being preferred.

The peculiar shape of the yielding body 2 is a matter of primary importance. Taken as a whole, it is concavo-convex with upwardly deflected edges. The central part 4 is flat and is surrounded by an upwardlyturned border or marginal part 5, the outer edges being of substantially uniform height except on the front or breast side, where the outer edge is invertedly arched or bowed below the plane of the side and back edges as shown at 6, thus obviating undue stress at this point, and permitting the adjacent lateral parts to yield backward and straighten out, when the lift is applied to the heel. The fiat central part 4 corresponds substantially in shape and extent with the plate-like body 7 of the fastener 3, which is preferably circular.

The fastener 3, it is to be understood, may be substantially like that shown on the first sheet of drawings of my said Patent No.

1,273,047, and the inner face of the middle part 4: of the lift is apertured as at 10 to receive the corresponding brads 11 of another lift where a pair are nested together, as described in said patent.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A heel lift, comprising a resilient body having a flat central part provided with a fastener embedded in and substantially coextensive in area therewith, and a marginal outer part inclined upward around said central part on all sides, the edge of said outer part lying in a plane except in front where its edge is centrally bowed therebelow,

1% nseeeee :2. A heel lift, comprising a resilient body and a fastener of substantially circular shape embedded in the central part thereof, said body havinga substantially circular flat central part co-extensive in area with said fastener, and a marginal outer part inclined upward around said central part on all sides, the edge of said outer part lying in a plane except in front Where its edge is centrally bowed therebelow. 10 Signed atChicage this 16th day of Oct, 1918.
